That would be awesome! I'm still getting the white puff of smoke out the exhaust on startup though after I drive it pretty hard/fast (80mph). I'm thinking I need to get the valve cover replaced, but I want to wait and see how the Range impacts oil consumption first.

***UPDATE*** After 1,000 miles, I have had to add 1 quart of oil. I just installed the Range yesterday, so I will report back after another 1,000 miles.

I've talked to my mechanic and the dealer's mechanic and my plan is to run 1,000 miles and see what the oil consumption is and then get the Range module and run another 1,000 miles and see what it is then. I'll post back with the results in a few months. Thanks!

I should've said I love everything about this Yukon except the oil consumption, and I really don't mind that if the engine holds together and I'm not dumping a bunch of money into it for repairs. I'll research this Range thing and maybe go with that. I'm guessing my mechanic would be able to install it? How can I find out if damage is already done to the engine? What should I have my mechanic look into? Thanks!

Hello all, I need help. I've got an '11 Yukon 5.3 with AFM, 114,000 miles and it seems to be eating around 2-3 quarts every 3000 miles. Good or bad, I don't drive it much and never tow anything, so oil consumption is difficult to read. I do get the puff of smoke when I start it after driving it "hard" which really just means running it 75 mph or accelerating quickly. What are my options? Should I just trade it in on a '14 or newer or what year doesn't have this issue? I'm not a mechanic, but I take it to my small town mechanic where I live who I know and trust and they do good work. Should I have them do something to it to try to fix it? I've only had it for about 8 months, man I wish I would've found this before I bought it.
